Just as it started to get cold I noticed that gear oil is coming out the top of the vent tube. It has been enough to cover my mud flap, and leave a 6" circle on the driveway floor. Any ideas why this would be happening now? Approx 8 months ago I changed the fluid when I replace axle seals, nothing has leaked out since then.
This is on a 83 CJ7, AMC 20 axle, one piece axle shafts.
